BAM is the formation of any 3 girls whose name's start with a B , an A, and an M . Often times BAM girls are the coolest shit you will ever discover and you will be jelous and if your not BAM girls like you to pretend to be because they are getting attention .
BAM people are never sluts and they actually try . There are no drugs, smoking or any of that gross stuff , but hey , they will accept a beer ;)

Person 1 :Hey did you see Brianne Ashley and Meredith ?!
Person 2 : Oh ya , they are so BAM !
